OpenWriteCompletedEventArgs.Result Property

Note: This property is new in the .NET Framework version 2.0.

Gets a writable stream that is used to send data to a server.

Namespace: System.Net
Assembly: System (in system.dll)

'Declaration
Public ReadOnly Property Result As Stream
'Usage
Dim instance As OpenWriteCompletedEventArgs
Dim value As Stream

value = instance.Result

/** @property */
public Stream get_Result ()

public function get Result () : Stream

Property Value

A Stream where you can write data to be uploaded.

You should check the Error and Cancelled properties before using the stream returned by this property. If the Error property's value is an Exception object or the Cancelled property's value is true, the asynchronous operation did not complete correctly and the Result property's value will not be valid.

The following code example uses the stream returned by this property.

Public Shared Sub OpenWriteCallback2(ByVal sender As Object, ByVal e As OpenWriteCompletedEventArgs)

    Dim body As Stream = Nothing
    Dim s As StreamWriter = Nothing

    Try

        body = CType(e.Result, Stream)
        s = New StreamWriter(body)
        s.AutoFlush = True
        s.Write("This is content data to be sent to the server.")
    Finally

        If Not s Is Nothing Then

            s.Close()
        End If

        If Not body Is Nothing Then

            body.Close()
        End If
    End Try
End Sub
